Application filed October 21. 1925. seria1 no. 63,813.

My present invention relates to watchcases, particularly those adapted to be worn on wrists'by attachment to a strap or straps, and aims to devise article; of the general character specified, which are simple in"con struction, easy, convenient and economical tofa'oricateand to assemble, which are neat and attractive in appearance, which are, novel and ingenious in the arrangemen t of the varionspartsand which for bat asiwell' as for other reasons are comiiieijciallyjyzilua l d d p ed bjfind .aJ a'di' a .i. t market. 'Other advantages of the invention'will in part be pointed out in' (le .tai hereinafter and will in part be obvious to those skilled in the art to which the pres ent invention relates.

In the accompanying specificat-ionI shalldescribe. and in theannexed drawing more or less diagrammatically illustrate, an*ill, u's"-' trative embodiment of thelpresentinvention. It is, 'ho.weve'r to be. clearly understood that my invention is not limited to the specific form thereof herein slio wn and described for purposes of illustration only."- 1

Referring to the drawing, whereinlI have 4 illustrated theaforesaid illustrative embodiment of the preient invention:

Fig. 1 is an edge View of such illustrative embodiment showing the principles of the present invention applied to a wrist watch case;

Fig. 2 is a front ment;

Fig. 3 is a rear plan ment; and

Fig. 4 isa detailed view. partly in cross section and partly inelevation, showing the watchcase proper of the aforesaidillustrative embodiment of' the present invention with the back member thereof removed.

Referring now to the aforesaid illustrativc embodiment of the present' invention. and more particularly'to' he drawing illustrating-the same, the aforesaid illustrative embodiment. of the presentinventionasheie shown and described comprises an outer frame member generally designated by reference character 10. Vhilevarious shapes and forms may be used for such outer frame member 10. I prefer that the same shall be substantially rectangular. as by being square and having the top and bottom frame memplan view of said embodiview of said .embo di bers 11 'and 12, respectively, and the side frame members 13 and 14, respectively.

Preferably the'frame member 10 is provided with means for carrying pintlcs or hinge. members to which the strap or straps for attaching the watch to the. wrist may be conveniently connected. For. this pur- POSQ'IRKEfBr to employ means integral with the framem'ember '10 for supporting such pintles or hingc members In the form shown, Iprovidefone or more pairs of cars, in this case t'wo pairs of cars, the cars 20 and 21. being continuations of the frame member 11, while the cars 22 and 23 are con- Lin'uationsof the framemember 12. Prefer ably the ears. 20, 21, 22 and 23 are slightly bevelled onthe front face of the frame member 10 corresponding to the face of the watch referencc'characters 25, 25. Ihepurposeofithis is to make the watchcase appear'm slope more gradually into the straplmeifiber or members and also to leave fewer exposed edges and to give the watchci 'se ja 'imore compact and attractive appearance.

iWitbin the'framc member 10, as by being attached to the interior of said frame member IO at a series of spaced points, is the watchcase proper, here generally indicated by reference character 30. The \vatchcase proper is provided with the usual bezel member 31. the back member 32, and the crystal 33 held within the bezel 31 in the usual man ner. Within the case 30 is the usual dial 34 behind which are the works or the movement of the watch itself.

It may' here be stated that the watcbcase proper may have any desired shape. For example, it may be polygonal rectangular, square, diamond-shaped, or it may be bounded by a curvilinear boundary. as by being oval or bybeing round, which is the particular form shown in the drawing. VVhatever form the watchcasc 30.1nay have. it is, as already indicated, attached to the frame 10 within the same at a series of spaced points. For this purpose, I prefer. thatv the watchcase 30 be attached to the frame 10 by having the bevelled portion 31 thereof so attached. In the form shown, the attachment is effected at a series of spaced points indicated by reference characters 35, 36. 37 and 38. The bezel portion 31 of the \vatchcasc 30 is attached within the frame member at the points designated by solder or other suitable metal joining: mean'szi .ltimay 'here be stated that if desired the bezel member 31 and associated portions of the watchcase pnoper; 30,. other than the back. member 32; may be made integraL-wrththe; frameLmems ber 10.

As indicated in Fig. 3 of the drav i'ng,

provides convenient means for carryingthe strap members which serve to attach the watch to the wrist of the wearer.

The advantagesof the foregoing construction are numerous and of great practical importance; "The watchcasc of. the present invention. is- "ery simple in. construction and may be readily and economically fabri- "eatedi- The watchcase also provides readily 10 there should be sutiicient clearance between available means for attaching the strap the frame member 30 and 'thebezefmember 31 within such frame to permltthe ready.

It may here be stated. that the strap member is provided with the usual buckle 54.- held on the loop. end5 5 of the strap member 50, such strap member being provided on the loop '56; for retaining the pointed end 57. of the other strap mem ber 51, which is, in the usual manner, pro

The constructionof. the aforesaid illustrative embodiment of. the presentinvention has, it is believed, been made snfiiciently clear from the foregoing description. Likewise the manner of assemblingsuch embodiment has, it is believed, been. made sufficiently clear in. the foregoing description, In use. the device possesses; many. advantages which may be briefly. summarized as fol- By means of the frame member provision is made for securely. and safely housing the watchcase proper. The frame member serves also to reinforce and strengthen the watchcase proper and to protect. the movement within the watchcase. The framealso members for s ecurin ii the watch to the wrist of the wearer. The construction is very neatfja'nd attractive in appearance, the arr'an'gementfof, the parts being novel and original, 'and'the watchcase of the present inyentioniwill' therefore find a ready and eiztensivesaleiin the market to which such strides :are directed. Other advantages of the present invention will readily occur to those skilled'intlie art to which the same relates. What claim as myinvention is:
